The brush cleans the inner socket of fittings sized for 7\/8 inch OD copper tube, using a 15\/16 inch brush diameter to make full contact with the fitting wall. Proper mechanical cleaning of both the tube end and the fitting socket is a foundational step in producing a leak-free solder joint. HVAC technicians, plumbers, and refrigeration mechanics use this type of brush as standard prep tooling on copper refrigerant lines, domestic water piping, and hydronic systems.\u003c\/p\u003e\n\u003cp\u003eThis fitting brush is suited for use on 7\/8 inch OD copper tube applications found in residential and light commercial HVAC refrigerant circuits, plumbing rough-in, and hydronic heating and cooling piping. It is used wherever copper fittings must be cleaned to bare metal prior to flux application and soldering or brazing. The economy design makes it practical to stock multiples for field service kits and shop use alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSized for 7\/8 inch OD copper tube fittings\u003c\/li\u003e\n  \u003cli\u003e15\/16 inch brush diameter ensures full-contact cleaning of fitting socket walls\u003c\/li\u003e\n  \u003cli\u003eEconomy construction suitable for high-volume field and shop use\u003c\/li\u003e\n  \u003cli\u003eRemoves oxidation and surface contamination to prepare fittings for flux and solder or braze\u003c\/li\u003e\n  \u003cli\u003eCompatible with both ducted and ductless system copper line applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style fitting preparation brush for 7\/8 inch OD copper tube used in HVAC refrigerant, plumbing, and hydronic piping applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed HVAC technician or plumber should perform copper tube preparation and soldering or brazing in accordance with applicable mechanical and plumbing codes, including IFGC and IPC requirements where relevant. Always depressurize and drain the system section being serviced before cutting or opening any copper line. Use this brush to clean the fitting socket interior, then clean the tube OD with an abrasive strip or emery cloth before applying flux. Never substitute cleaning with flux alone.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube OD Compatibility\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrush Diameter\u003c\/strong\u003e: 15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Copper tube fitting socket cleaning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem Compatibility\u003c\/strong\u003e: Ducted and ductless\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DIVERSITECH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: b-129\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DIVERSITECH","offers":[{"title":"Default Title","offer_id":51138663940402,"sku":"B-129","price":25.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532784.png?v=1778261379","url":"https:\/\/voomisupply.com\/products\/diversitech-b-129-copper-tube-fitting-brush-7-8-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
